The Upper Leather Flexing Tester evaluates the flexing endurance and resistance to cracking of shoe upper materials (vamp leather) by applying repeated zigzag flexing. It simulates the bending and stretching stresses experienced during walking and provides an objective assessment of material durability, wrinkle formation, and crack development.
Applications
(1) Men’s and women’s leather uppers: High-quality dress shoes, casual shoes, and sports shoes.
(2) Synthetic leather and PU uppers: Footwear used in casual, sports, and work shoes.
(3) Shoe vamp materials: Leather, PU, and other upper materials before assembly into finished shoes.
(4) Footwear R&D: Assessing new upper materials or surface treatments for resistance to flexing.
(5) Quality control in production: Evaluating consistency and durability of upper materials before assembly.
(6) Laboratory testing: Material research for wear, wrinkle formation, and cracking resistance.
Standards
(1) GB/T 20991-2007 — Test Methods for Personal Protective Equipment Shoes
(2) EN ISO 20344-2012 — Personal Protective Equipment — Footwear — Test Methods
(3) SATRA TM25 — Upper Flexing Resistance Test
(4) ISO 4643 — Leather — Determination of Flexing Endurance
(5) ASTM D1052 — Standard Test Method for Flexing Endurance of Leather
(6) BS 5131 — Footwear Testing — Upper Flexing
Features
(1) Measures upper leather or synthetic materials’ resistance to flexing, wrinkles, and cracking.
(2) Simulates real-world stresses experienced by the shoe vamp during walking.
(3) Provides visual assessment criteria to quantify material durability.
(4) Supports multiple testing stations (4 or 12 samples) for higher throughput.
(5) Adjustable flexing speed, stroke, and clamping angle for precise control.
